The results of LDV measurements and investigation of the detailed flow field in a radial inflow turbine nozzle are presented. The flow velocities were measured at upstream, inside and downstream of the nozzle blades for two different mass flow rates, using a three-component LDV system. Results are presented as flow turbine cascades because of the radial pressure gradients and the incidence effects. Although they show the existance of the leading edge vortices, the of passage vortices are either too weak or they do not at exist. The shape of leading edge vortices depends strongly on the incidence angle.
